The 92-year-old described the modern green movement as a 'religion', which used guilt to gain support.
Speaking about climate change, he said: 'I'm not worried about sea-level rises.'
He added: 'At worst, I think it will be 2ft a century.'
Slamming environmentalists, he said: 'It just so happens that the green religion is now taking over from the Christian religion.
'I don't think people have noticed that, but it's got all the sort of terms that religions use. The greens use guilt. You can't win people round by saying they are guilty for putting CO2 in the air.'
Mr Lovelock said he was a firm supporter of nuclear power and even voiced his support for fracking – the controversial process of extracting gas from rock deep underground, opposed by the green movement.
He said: 'Gas is almost a giveaway in the US at the moment.
They've gone for fracking in a big way.
'Let's be pragmatic and sensible and get Britain to switch everything to methane. We should be going mad on it.'
... It's a much better route to go than so-called “sustainable development”, which is meaningless drivel.IOW: AGW = TFBS.
